linux下挂载磁盘报错“Structure needs cleaning”。系统之前一直正常，突然掉盘后无法挂载，尝试手动挂载后报错：

root@pbs:~# mount -a
mount: /mnt/data/1: mount(2) system call failed: Structure needs cleaning.

对于重装linux系统或者掉盘的用户常常遭遇挂载磁盘报Structure needs cleaning的问题。

首先查看磁盘是什么文件系统？

root@pbs:~# blkid

ext4文件系统，使用命令 fsck.ext4 /dev/sdb1修复，

如果是xfs文件系统，使用命令 xfs_repair -L /dev/sdb1修复，

Superblock needs_recovery flag is clear, but journal has data.
Recovery flag not set in backup superblock, so running journal anyway.

一般情况修复后可正常挂载。如果修复后还是无法挂载，可能你就需要重新格盘
